You have a jar of marbles in front of you with the following colors: 7 - red, 12 - blue, 6 - yellow and 9 - white. what are the odds of selecting marble that is not blue, replacing it and then one that is blue?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
